Methods for producing objects from precursors and use of radically crosslinkable resins in addition production methods

摘要

The present invention is a method for producing an object from a precursor, comprising the following steps: I) obtaining a layer of a constituent material corresponding to a first selected cross section of the precursor, the radical cross-linked resin being bonded to a carrier. II) depositing a radical cross-linking resin on the previously applied layer of the component material into a further selected cross section of the precursor bonded to the previously applied layer Depositing on a previously applied layer of component material so that an additional layer of the corresponding component material is obtained; III) repeating step II until the precursor is formed, at least The deposition of the radical crosslinkable resin in II is performed by exposing and / or irradiating a selected region of the radical crosslinkable resin corresponding to each selected cross section of the object, wherein the radical crosslinkable resin is at least 5 mPa · s 0000mPa · s or less viscosity (23 ℃, DIN EN ISO 2884-1) relates to a method having. In this method, the radically crosslinkable resin comprises a curable component in which an NCO group and an olefinic CＣC double bond are present, wherein the curable component has a molar ratio of NCO group to olefinic C ＝ C double bond. Is 1: 5 or more and 5: 1 or less. In this method, the precursor obtained after step IV): IV) step III) is converted, at least in part, from the NCO groups present in the radically crosslinked resin of the obtained precursor so that an object is obtained. A step of treating under conditions sufficient to trimerize to a nurate group is performed after step III). The present invention further has a viscosity (23 ° C., DIN EN ISO 2884-1) of not less than 5 mPa · s and not more than 100,000 mPa · s, and has a curability having an isocyanurate group, an NCO group, and an olefinic C ＝ C double bond. The present invention relates to the use of a radically crosslinkable resin containing a compound in an addition production method. Finally, the invention relates to a polymer obtainable from the crosslinking of such a resin.
